Whats the hotkey for changing viewer rotation?
There is a solution to this, but it's a work around.

You can set an empty at the center of your focal target, and parent your camera to it.

To do that select the Camera 1st, then while holding the Shift key select your Empty.

Then on your keyboard Ctrl+P to parent.

To get the turn table effect go into camera view Numpad 0, then select your empty and rotate it about the Z Axis. 

Then use middle mouse as your trackball.
